It depends of course on the specific material, but it being nano-sized makes no difference at all to the NMR spectrum. Nuclear Magnetic Resonance works on the principles of excitation and emission of the nucleus of the atoms. Only certain nuclei are capable of being monitored using NMR spectroscopy. What is required is a nucleus with an odd number of particles in it (such as carbon-13, hydrogen-1, fluorine-19, etc) which have odd spin. However such nuclei are common to most materials and therefore should allow the use of NMR for characterisation of nanoparticles.

What else can I help you with?
What type of nuclei are NMR active?
Nuclei with a non-zero spin quantum number, such as 1/2, 1, or 3/2, are NMR active. Common NMR-active nuclei include 1H, 13C, 19F, and 31P.
What is nmr stand for?
NMR stands for Nuclear Magnetic Resonance, a technique used to study the structure and properties of molecules by analyzing the magnetic properties of atomic nuclei.
How do you get proton decoupled spectra of 13C NMR?
Proton decoupling in 13C NMR spectroscopy is achieved by irradiating the sample with radiofrequency pulses that flip the nuclear spins of the protons, effectively decoupling them from the carbon nuclei. This eliminates the splitting caused by proton-carbon coupling, resulting in a simpler and easier-to-interpret 13C NMR spectrum.
What is cosy nmr?
'COSY NMR' stands for 'Correlation Spectroscopy Nuclear Magnetic Resonance.' It is a technique used in NMR spectroscopy to establish correlations between different protons in a molecule, providing information about the connectivity of atoms within a molecule. This method is particularly useful in determining the structure of organic compounds.
Can NMR be done for gaseous samples?
Yes, NMR can be done for gaseous samples. NMR instruments can be equipped with special probes and accessories to handle gaseous samples, allowing for the analysis of molecules in the gas phase. This is often used in the study of chemical reactions, gas phase structure determination, and environmental analysis.
What is the difference between NMR and FT- NMR instrumentation?
NMR (Nuclear Magnetic Resonance) spectroscopy measures the absorption of electromagnetic radiation by nuclei in a magnetic field, providing structural and chemical information about molecules. FT-NMR (Fourier Transform-NMR) is a technique that enhances the speed and sensitivity of NMR by using Fourier transformation to convert the time-domain signal into a frequency-domain spectrum, allowing for higher resolution and improved signal-to-noise ratio. Essentially, FT-NMR is a more advanced and efficient method of performing NMR spectroscopy.
How may words can you get out of characterisation?
Some words that can be formed from "characterisation" are: Character Irate Action Nation Reaction
When was Journal of Biomolecular NMR created?
Journal of Biomolecular NMR was created in 1991.
How is double bond in a molecule detected?
you can use IR, NMR to determine the presende of double bond
What are different types of nanotechnology?
Nanomaterials, Nanomachines, Nanofactories
What is difference between characterisation and standardisation?
Characterisation is the character of a person or the way someone acts, standardisation is the standard process of something that is the basic and or standing process
What has the author George Constantinidis written?
George Constantinidis has written: 'Growth and characterisation of single CuInSe2 crystals' 'Electrical characterisation of doped CuInSe2 single crystals'
How many unique 13C NMR signals are present in the compound?
The compound has three unique 13C NMR signals.
What does characterisation mean in dance?
Characterisation in dance refers to the process of embodying and expressing a specific character or persona through movement, gestures, and facial expressions. Dancers use techniques such as body language, style, and emotional expression to convey the traits, motivations, and stories of their characters. This enhances the narrative of the performance and allows the audience to connect more deeply with the characters portrayed. Effective characterisation enriches the overall experience, making the dance more engaging and relatable.
What type of nuclei are NMR active?
Nuclei with a non-zero spin quantum number, such as 1/2, 1, or 3/2, are NMR active. Common NMR-active nuclei include 1H, 13C, 19F, and 31P.
What range of electromagnetic radiation is used in NMR?
Nuclei in NMR spectroscopy primarily interact with radiofrequency electromagnetic radiation, typically in the range of 60-900 MHz for protons.
Why must deuterated solvents, such as D2O and CDCl3, be used to prepare NMR samples?
Deuterated solvents are used in NMR samples because they do not interfere with the NMR signal of the compound being analyzed. Regular solvents contain hydrogen atoms that can overlap with the signals of the compound, making it difficult to interpret the NMR spectrum. Deuterated solvents replace these hydrogen atoms with deuterium, which does not produce signals in the NMR spectrum, allowing for a clearer and more accurate analysis of the compound.
